Estate of Richard Tousey, astronomer, and a senior scientist involved with NASA's solar photography project
Skylab, the United States’s first space station, "served as the greatest solar observatory of its time" [NASA. Skylab Mission Pages, online] providing opportunities for study of the the sun that were not possible with earth-based telescopes. The Apollo Telescope Mount, which took photographs of the sun at various wavelengths, was operated manually by the astronauts who loaded and replaced canisters of film when on spacewalks. The film was then processed and printed when returned to earth, and the intensity of the x-ray photograph color-contoured to show the range of heat.
